Definitions

  • the invention relates to a hybrid system for the use of wind power and solar energy nor the preamble of claim 1. Such systems are used alternatively for the production of electrical energy.
  • hybrid energy systems have been developed, as described, for example, in DE 296 21 822 U1 and in DE 296 07 243 U1.
  • Such systems consist of the usual rotating wind turbines, attached to the frame structures large-scale solar modules and are integrated electrotechnically.
  • These large-area solar modules consist of a large number of individual and interconnected solar cells. Initially, due to their dimensions, such systems can only be integrated poorly into the landscape or even into residential areas.
  • a major disadvantage of such systems is that large-area Sofamwdule generate a high wind load that must be applied by the wear-the frame of the system. This leads to even more expensive constructions.
  • the installation height of the solar modules is not important for energy production, ie they can be installed just as well on the floor.
  • the production of solar modules is very expensive and waste-intensive, since the individual solar cells must be tailored to fit before they are arranged in solar modules and electrically interconnected.
  • the invention is therefore based on the object, the wind vane elements and so that the solar cells optimally in a generic hybrid plant reduce and thereby the efficiency of the wind turbine part and the Solar system part increase.
  • the particular advantage of the invention lies in the fact that the individual solar cells are not electrically connected to rigid modules. This makes it possible, by means of a corresponding scanning program, to combine the electrically optimal performance characteristics of the individual solar cells. This is necessary for an optimization of the energy yield, since the system represents a light-flooded object and the changing state of the sun and the movement of the solar cells in the wind influence the irradiation or shading of the individual solar cells.
  • By means of dynamic interconnections of the respective same energy levels of solar cells serial, parallel or combined interconnections of solar cells are realized according to the electrical power principle.
  • the resulting diversity of current orresdominierender circuits allow the use of a solar inverter for feeding in the grid. This eliminates the intermediate storage in batteries, whereby the utility value is significantly increased.
  • the sporadic voltages generated by the piezocrystal transducers are suitably converted into useful electrical energy, for example, by buffer capacitors, in an inverter circuit or by pulse transformers. Since every imaginable, introduced into the piezoelectric crystals bending, torsion, etc. leads to electrical voltages, wind energy conversion is given even with constantly changing wind directions. It is expedient for reasons of cost not to transplant the piezocrystal transducers directly into the branch elements, but to classify them into pluggable coupling elements. As a result, the responsible for a large relative deformation, different material properties can be realized very easily.
  • This type of coupling also makes it very easy to set up a network of many such coupling elements in the crown boxes, which has an advantageous effect on the effectiveness of the system. Since in an advantageous manner the parent elements and the pile elements are designed to be plugged together, such a system can be set to generate energy to any energy requirement but also to any design requirement. Also very advantageous is the design of the solar wind elements in the form of thin-film solar cells or solar films. They are light and flexible like leaves and not so easy to heat because they are cooled anytime and easily by any small wind draft.
  • the hybrid plant for the use of wind and solar energy is approximately comparable in shape to the shape of a tree and therefore consists of one Trunk 1 and a crown, consisting of crown elements 2 and Kronengeagonist 3.
  • the Kronenge65 3 is made connectable via couplings 4 with the crown element 2.
  • Fig. 2 shows a crown element 2 with a plurality of couplings 4, which are arranged distributed in a loose or in a strict order on the circumference of the crown element 2.
  • a flexible coupling element 5 is used in each of the clutches 4, which is connected on the side remote from the stem with a first-order branching element 6.
  • the branch element 6 is also equipped with a coupling 7. Similar to the tree design, further branch elements 6 'of the second order and branch elements 6 "of the third and further orders follow the branch element 6.
  • further coupling elements 5 are inserted at preferred points in the same manner ,
  • each Windolarelement 8 is designed to accommodate wind loads and for receiving solar energy.
  • Each Windsolarelement 8 is connected via a connecting line 9 with a computer not shown, which scans for a program each of the Windsolar electrode 8 in a short cycle, comparing all simultaneously determined solar energy values together and the Windsolar electrode 8 linked with the same energy level. 4.
  • the structure of the coupling element 5 is shown in FIG. 4. Thereafter, radially evenly distributed piezocrystal transducers 10 are cast into the flexible coupling material, which are then connected via leads 11 to an electronic unit, not shown.
  • the trunk 1 and the crown with all its elements is preferably made of a plastic, wherein the material properties in the area where the piezoelectric crystal transducers 10 are used, has greater flexibility, such as the material properties in the other areas. It is most expedient if the flexibility of the location region of the piezocrystal converter 10 is only so great that the dead weight of the connected elements is borne and the remaining elements are rigid. Thus, the largest mechanical deformation is directed to the piezoelectric crystal transducer 10, which convert the kinetic energy occurring into electrical voltage.
  • the plurality of wind solar elements 8 are more or less exposed to the wind and the sun, with the individual wind solar elements 8 being in a different orientation to the sun and the wind and partially or completely obscured by other wind solar elements 8.
  • individual wind solar elements deliver 8 different solar energy values.
  • these solar energy values are constantly changing due to the changing state of the sun and the constant changes in the direction of the wind solar elements 8 caused by the wind.
  • the large number of individual and different voltage and current values are fed in a short cycle to a computer, which detects and compares all these values.
  • a selected performance diagram is shown in FIG. 5, according to which each wind solar element 8 has different solar energy values with respect to a specific temporal moment.
  • the computer assigns the wind solar elements 8 to matching solar energy values and combines the same values having Windsolaretti 8.
  • FIG. 5 shows three different power curves of wind solar elements 8 for illustrating the principle of scanning the power level of the wind solar elements 8.
  • the difference in the power level of the wind solar elements 8 is based, as already described, on the different orientation to the sun, caused by wind movements, which can lead to shadowing.
  • the sampling is based on the principle of the sampling method, whereby fast A / D converters sample and digitize the individual power curves according to the sampling frequency and the quantization levels.
  • the graph in FIG. 5 shows three power curves of different wind solar elements 8 over a certain sampling period. The markings in the three power curves indicate that the same energy levels occur on the different power curves during the scan.
  • the computer assigns the wind solar elements 8 to matching solar energy values and combines the same solar energy values having Windsolarieri 8. This in many of a few thousand solar cells and a corresponding clock rate is the guarantee of optimization over the entire power spectrum of the wind solar elements used. 8 The same wind solar elements 8 but also burdened by the wind and give this load.
